GekkoScience Compac BM1384 Stickminer Official Support Thread

Ok, I tried with different positions, but I got the same results. 2 of 3 are (sometimes) working. Mostly only 1 is working, sometimes none of them ...

Yes, I'm using the arctic fan (and it's operated by a rasp pi 3).

strange, they should work. Most likely nothing to do with the hub.
Did you adjust voltage with the tiny nob and measured it?

[raiding]

Yes, I did. They are all @0.79V

too high for both 250 and 300.
if "flat" at 5pm indicates about 800mv, try 2pm for 250 and 3pm for 300 (approximate).
I might remember incorrectly, but should be in the ballpark.

Ok, I changed it. But the results are the same: Only 1 of 3 is recognized.
I tried with Y-cables, too -> cgminer isn't detecting a single gekko with it.

after you change your cable arrangement, you'll have to restart pi or computer, otherwise they would not start (at least in my case).
that, or there is something weird in your setup. i would start with just one and see if everything works fine.

[raiding]

Yeah, I mostly "reboot" my pi physically after making changes and syncing the filesystem ...
May you can point me on something, I didn't think about (I'm a noob at least with advanced linux-skills).
Are there other "common mistakes" in setting up a raspberry pi based miner with gekkos?

edit: 1, 2 or all geekos at once it doesn't make a difference, when MHz > 150. They seem to work very randomly ...

don't plug your USB3 hub in the RPI.
use a USB2 hub as a bridge.

RPI -> USB2 hub -> USB3 Hub

Yes, you're right.
Sadly none of the raspberry-models has a build-in USB 3 ... I'm using only USB 2.0 hubs

Which pool you are mining to? Some pools will disconnect you because of a small hashing speed.
Eligius was OK with my sticks.

I'm using solo.ckpool.org and de.ckpool.org as backup

I know that kano.is ckpool does not allow low hashing miners. He disconnects them.
EDIT: apparently, incorrect Not sure about solo, but it is run by the same two operators (kano and -ck), as far as I remember.

Per the info on their website their solo pool is geared to sticks and other very low yield miners for lottery mining.

Ok, i stand corrected  .
regular kano.is definetly disconnects low hashing devices.
i don't have any more suggestions..

150MHz is working over days

[gt_addict]

So ive got a bitshopper version of the gecko #10000031 (yep an early one) and its suddenly going crazy. Set to 215mhz for the past 12 days and been running at 12Ghs no problem. Until today. It drops out and then when hotplugged it comes back and does 18-20Ghs and a ridiculous high HW Error rate and gets really hot.

Ive hotplugged it few times and each time the same thing. The other two sticks running off the same hub and pi are fine (ive got a fan pointed at all of them too).

Anyone have any ideas?

[sidehack]

I would guess the ASIC is cooked.

[gt_addict]

Well she's had a good life since I've known here. Time to use her as a template for the other two gekkos so I can mount them on a big copper heatsink.

[gt_addict]

Well what d'ya know, she lives!  Albeit at a lower hashrate than before 11.5Ghs avg. Meh, aslong as she chooches and gets shares then so be it.

[enrajrnaki]

I am new. Very new. I downloaded all you linked to. Made changes as supplied.

1) where to extract
2) how to run
3 any other info on running the compact BM1384

Please help. I got to and there connected to a hub.

In devices they do show up. But I cannot make the work

best regards
